PCB designers start by creating two electronic documents, a schematic and a layout. (They are also known as printed wiring boards, or PWBs, before they are populated with components.) The purpose of the PCB is, of course, to provide the structural support to hold the components in place and to provide the wiring needed to connect signals and power to the components. Printed circuit boards typically contain thousands of components. In order to understand how a circuit board can be hacked, it’s worth reviewing how they are made.

Fortunately, the means to shore up those points are relatively straightforward, and many of them simply amount to good engineering practice. We’ll take you on a tour of some of the best-known weak points in printed-circuit-board manufacturing. We know much about malware and counterfeit ICs, but the vulnerabilities of the printed circuit board itself are only now starting to get the attention they deserve. And there have been more than a dozen documented examples of such system-level attacks. Even so, the possibility of carrying out such a stupendous hack is quite real. This claim has been roundly and specifically refuted by the companies involved and by the U.S. In 2018, an article in Bloomberg ­Businessweek made the stupendous assertion that Chinese spy services had created back doors to servers built for Amazon, Apple, and others by inserting millimeter-size chips into circuit boards.
